Method of preparing acylisocyanates |
摘要 |
The invention relates to a novel process for the preparation of acyl isocyanates which consists in reacting oxalyl chloride with an N-trialkylsilylcarboxamide or an N,N-bis(trialkylsilyl)carboxamide. The process makes it possible to obtain acyl isocyanates in good yield, in particular acyl isocyanates derived from aliphatic amides, and under simplified reaction conditions. |
